LOCOMOTIVE.

Application filed March 7, 1910.

Be it known that I, FRANK L. Snssrous, a citizen of the United States, residing at Columbus, in the county of Franklin and State of Ohio, have invented certain new and useful Improvements in Locomotives, of which the following is a specification, reference being had therein to the accompanying drawing.

This invention relates to improvements in electric locomotives and more especially to thejournal boxes for the axles and the means One of the objects of my invention is to provide, in an electric locomotive having connecting rods, means for adjusting the distance between the axles in conformity with the length of the rods.

Further objects are proved details of journal box construction and mounting. 5

In the accompanying drawings-Figure1 is a side view of an electric locomotive provided with journal boxes and adjusting means embodying the invention. Fig.2 is boxes and connected parts on a larger scale. Fig. 3 is a vertical sectional view on line 3+3, Fig. 2. Fig. 4 is a horizontal section on line 1 4, Fig. 3. Fig. 5 is a side view of the pedestal. Fig. 6 is a plan view of the same. Fig. 7 is a top plan view of the brace and dowels. Fig. 8 is a side view of the same. Fig. 9 is an elevationof the gib. Fig. 10 is a central vertical section of the same.

Referring to the drawings, A represents as a whole the frame of the locomotive. This frame is preferably constructed ofv rolled steel sections. As shown in the drawings, the frame consists of end parts 1,1, each comprising a single channel section, and side parts 2, each comprising a lower channel section 2 secured to the end channel sections and an upper channel section 2 secured to the lower channel section 2*. Each of the lower channel sections 2 is made up of three parts each being separated to provide openings 2 for the journal boxes and associated parts to be described.

3, 3 represent the main axles and 3 3 represent the locomotive supporting wheels secured to the ends of the axles 3 3 betweenwhich there extends a connecting rod 3. The journal boxes for the axles 3 are each composed of upper and lower separable parts 4 and 5.

6 represents the main bearing portion of the box and is suitably babbitted. It engages with the journal part of the axle and 7 lies within a suitable aperture 1n the main part 4: of the box.

At 7 are indicated lubricating ducts in the part 4i for the main bearing 6.

The lower flange of the upper channel section 2 extends above the journal box opening 2. Between this flange and the box are interposed springs 9 through which the weight of the frame is transmitted tothe box, axle and wheels. The springs are fitted at their lower ends in recesses 10 in the box and at their upper ends fit over bosses 11 bolted to the under sideof the flange 8. At its sides the box is formed with vertical 1 straight channels 12. to provide certain im- 5'1 13 is a guide frame for the journal box comprising a U-shaped plate 14 which fits against the outer face of the frame 1 around the opening 2 and is riveted to the frame as indicated at 15. The end elements of the frame constitute pedestals for the box, these being connected "together by the longitudinal top member. The pedestals are provided with integrally formed guides 16 which extend within the limits of the opening 2 both laterally inward to points substantially in line with the channels 12 of the box and These guides are I thence toward the box.

faces 17 which incline upward and outward in the reverse from the ordinary direction. There is also provided abottom brace 18 the lower part of the opening 2 and unites the pedestals with each other. The under faces of the guides 16 of the pedestals are formedwith recesses 19 and the top face of the bracewith corresponding recesses 20 and in these recesses fit dowels 21 which give a very strong connection between the brace and the guides against the horizontal strains transmitted from the wheels, axle and journal box. I I

22 indicates bolts which pass up through the brace and through the dowels and are screwed into the bottoms fthe guides 16.

Box-engaging adjusting gibs are shown at 23. They arearrangedone at each side of the journal box, interposed between the guides 16 and the box, and are formed with inner vertical straight faces which have a sliding fit within They are also formed on their outer faces toward the guides with channels 24: tapered which extends across the channels 12 of the box.v

n have provided not only with its guides,

to correspond and have a sliding fit with the tapered faces 17 of the guides. The gibs are vertically adjusted, to closely confine the journal box but allow of its vertical play, by means of screws 25 which engage threaded holes in the upper ends of the gibs and which pass up through the flange 8 of the locomotive frame A.

26 is a fixed nut on the screw 25, being pinned thereon at a suitable point to bear on v the under side of the flange 8.

27 is the head of the screw arranged above the flange 8 in an accessible location allowing of the adjustment of the gibs from time to time with great convenience.

28, 29 are jam nuts on the screw above the flange 8 by which the screw is held securely in its adjusted position. 30 is an angle washer interposed between the jam nuts and the said flange and shaped to fit the upper inclined surface of the flange.

Inthe operation of adjustment the gibs are held from turning by their engagement with the guides 16 and may be forced down ward to hold the journal box more closely or may be drawn upward to leave it more free, by the action of the screws 25 which engage the gibs by their threads and are held from vertical movement in the flange 8.

The openings in the flange 8 through which the screws 25 pass are indicated at 31 and enlarged or elongated to allow the screws to shift as may be required to accommodate the horizontal shifting of the gibs.

It will be observed that by my invention I means for adjusting the engagement of the slidable journal box but also means for regulating within narrow limits the distance between the two axles. When a connecting rod is used, as in the present case, this adjustment is very essential as it is necessary for eiiicient and proper operation that the distance between the axles be the same as the length of the rod. It will be obvious that either of the boxes may be moved laterally as desired by moving one gib upward and the other downward, or vice versa. This need for horizontal adjustment is especially great in the case of a locomotive having a frame made up of structural steel parts. A separate bearing guiding frame is necessary when a structural steel frame is used and this'cannot be riveted or otherwise attached to the frame with suflicient accuracy to secure it at that exact relative location of the machined surfaces which is essential.

What is claimed is 1. In an electric locomotive, the combination of the side frame having a downward directed opening and a horizontal flange above the opening, the pedestals attached to the frame at the opening, the said pedestal extending under the flange and having guides inclined downward and inward toand a journal box engaging the tgibs, substantially as set forth.

3. In an electric locomotive, the combination of the side frame having a downward directed opening, a guide frame comprising pedestals and extending partly around the opening and attached to the frame and extending within the opening where it is pro vided with guides, a brace, dowels inserted in the brace and in the lower ends of the pedestals, bolts passing through the brace and dowels and into the pedestal, vertically adjustable gibs engaging the guides, and a journal box'engaging the gibs, substantially as set forth.

4.
